The BelAire 6312H Iron Series is a 10 HP, two-stage compressor delivering 35 CFM at 100 PSI and 32 CFM at 175 PSI, built around a solid cast-iron pump with automotive-style rod bearings and wrist pins. Those bearing and pin assemblies are designed to handle repeated reciprocating loads with less friction than plain bushings, making them a meaningful durability feature for compressors that accumulate long operating hours. The horizontal layout keeps the machine under 49" tall, while the three-phase motor and factory-installed magnetic starter are suited to professional shop installations. Note: published specifications conflict on voltage, so confirm the correct electrical configuration before ordering.
The two-stage pump compresses air in stages with cooling between them, allowing the compressor to reach 175 PSI while managing the heat generated during compression. An aftercooler further reduces discharge-air temperature before the air reaches the tank, helping more moisture condense at the receiver instead of traveling through the shop's air lines. The fully enclosed high-flow belt guard protects the drive components while maintaining airflow around the flywheel, and the oil sight glass makes routine level checks simple. The pump uses belt drive and splash lubrication, while the manual tank drain requires regular condensate removal as part of normal maintenance. For moisture-sensitive applications, BelAire recommends the CPXHT50 dryer, sold separately.
This compressor is built for multi-bay automotive shops, fleet and truck maintenance facilities, fabrication shops and other operations where several technicians or high-demand pneumatic tools may be drawing air simultaneously. Its 73" × 24" footprint and 49" height make the horizontal configuration particularly useful in low-ceiling buildings or beneath mezzanines. The machine weighs approximately 830 lbs, so plan the delivery route and installation surface accordingly. The source describes the compressor as dual-voltage 208–230V three-phase, while one specification field lists 460V; because those are materially different electrical requirements, have a licensed electrician and the manufacturer confirm the correct voltage before purchase.

Confirm the Tank Size Before Ordering
Published specifications conflict on the receiver capacity. The product title and specification record state a 120-gallon horizontal ASME tank, while the manufacturer's feature line describes an 80-gallon air reserve, wording that also appears on BelAire's smaller models.
Because tank capacity is a major part of this purchase, confirm the tank size with us in writing before ordering. We will verify the exact configuration with BelAire.
Certification, Stated Plainly
The tank and safety valve are ASME rated, which applies to the pressure vessel that stores compressed air. It does not constitute an electrical safety listing.
BelAire's published data for this model does not claim a third-party North American electrical safety listing. If your insurer, safety officer or local inspector requires one for shop equipment, ask us to confirm the available documentation before ordering.
Shipping & Delivery
Ships by freight to the lower 48 states, secured on a pallet. At 830 lbs, plan for a loading dock, forklift or pallet jack with a hard, level path from the truck to the door. If those are unavailable, terminal pickup with a suitable trailer may be easier.
Residential deliveries carry an additional fee, quoted with shipping at checkout.
Inspect before signing. Check the belt guard, gauge, motor housing and tank welds for damage. Record any issues on the delivery receipt with the driver present and take photographs before accepting the shipment.
Warranty
This model is listed with a 2-Year bumper-to-bumper factory warranty for consumer and commercial use, with no additional purchase required.
The warranty document supplied with the unit governs coverage, so keep it with your purchase records. If a problem develops, do not disassemble the pump, motor or electrical enclosure before opening a claim. Contact us first so the manufacturer can inspect the affected components intact.
